What is the flow analysis?
The flow analysis (FIA) is a microchemical technique developed in Denmark and in the United States, for chemical analysis of sample materials in the flowing stream of the supporting liquid. This compatible computer process has become the most popular type of flow analysis and replaces manual methods using laboratory pipes and beaker. The FIA is used in monitoring industrial processes in the food, beverage and pharmaceutical industries; in agriculture; when monitoring the environment, such as water testing for contamination; And in the sciences of life.
In the flow system, the reagents together with the supporting solution are pumped in a continuous manner, stirring coils and the detector flow center. And The agent is a substance used in chemical reactions to detect, measure or produce other substances. A small sample of a substance to be tested when injection into a liquid solution, where it combines with one or more agents. The following chemical reactions result in a color change,that is measured in the detector. The whole process can be carried out in approximately a minute with a much smaller sample than required in manual processes.
There is a wide range of flow injection analysis. The simplest forms are cheap, manually controlled units used to perform cheap tests or tests to determine the presence of a chemical or substance. For biomolecules tests, more complex, completely automated systems such as blood hormone levels are offered. Automated systems range from affordable units with individual chambers to much more complicated more chamber configuration needed for more difficult applications.
flow analysis has become a cheap method for detecting the presence of toxic substances in rivers or waste water. Testing near industrial sites is carried out for monitoring if the polluting substance is released. Existing FIA methods can detainEdge the presence of ammonia, arsenic, mercury, cyanide, phosphate and nitrate in water.
Agriculture and forestry also use the flow analysis to perform soil testing. Soil on -site tests can be very useful for crop management specific to the location. Based on the results of the test, growers can determine which nutrients may be supplemented to obtain maximum crop yields. The forest department uses the FIA to determine the health of land in state and national forests.
Flow injection analysis was helpful in the help of pharmaceutical companies in accordance with strict regulations regarding the quality control. Several samples are taken from each drug dose and the tests are performed to ensure that the efficiency is stable; If the prescription requires 250 mg of penicillin, it is important that each capsule contain exactly this amount. FIA is also used to test vitamin, hormone and chemicals in blood. Biologists use the FIA to study living cells, monitor chemical processesAnd studying the body produces antibodies when substances called antigens are introduced.flow analysis offers many advantages over traditional analysis of tubes and beakers. The procedure is cheap and fast and often causes results in less than a minute. The automated flow of liquid provides a uniform test environment and offers technicians another level of protection for handling toxic substances or testing toxic substances. The device is also compatible with the computer and provides faster analysis and at the same time limits possible data entry errors during manual testing.
